Analysis of a large linear antenna array of uniformly spaced thinwire dipoles parallel to a perfectly conducting plane
Abstract
A method of moments solution is presented for the analysis of a large linear antenna array of uniformly spaced thinwire dipoles parallel to an infinite perfectly conducting plane. A single piecewise sinusoidal expansion and testing function per dipole is used in a Galerkin procedure. This results in a symmetric Toeplitz generalized impedance matrix requiring approximately 2Nsquared multiplications and divisions to determine the unknown dipole currents. The solution corresponds to a savings of a factor of N/6 over a Gaussian elimination solution. Computed results are given for a 1000element dipole array.
